An antibody is a Y-shaped protein molecule that is used in defense against an antigen, such as a virus. It is a means of protecting the organism from invading, harmful life forms. The ends of the Y-shaped proteins bond with antigens “labeling” them for attack by other parts of the organism's immune system.
